Q & A

Why is it important to protect yourself online?

Protecting yourself online is crucial because your safety, finances, credit, and personal data are at risk when engaging with digital technology. Secure practices help prevent theft and safeguard sensitive information.

What is the first step in securing a wireless network at home?

The first step in securing a wireless network is to create an encrypted Wi-Fi connection, ensuring that unauthorized users cannot access your network and potentially steal unencrypted data.

How can power surges affect computer equipment?

Power surges can damage computer equipment by sending excessive electrical voltage into devices, even when they are turned off. Using a surge protector can prevent such damage from power spikes, brownouts, or electrical noise.

What is a surge protector, and why is it important?

A surge protector is a device that shields electronic equipment from power surges. It is essential to prevent damage to devices like computers, phones, and modems during power spikes.

What is an Uninterruptible Power Supply (UPS), and when is it used?

An Uninterruptible Power Supply (UPS) is a backup power system that provides temporary electricity during power outages, preventing data loss and allowing users to shut down their equipment safely.

Why should you use a cable lock for your laptop?

A cable lock is important for securing a laptop in public spaces, such as hotels or cafes, to prevent theft. It physically attaches the device to a fixed object, making it harder for thieves to steal.

What should you do if your laptop or mobile device is stolen?

If your device is stolen, contact law enforcement immediately and use location-tracking features like 'Find My Device' or 'Find My Phone' to help locate it. Do not attempt to retrieve the device yourself.

What is the importance of backing up your devices?

Backing up your devices ensures that your data is protected in case of device theft, hardware failure, or a ransomware attack. Regular backups minimize the risk of losing important files.

Why is it risky to rely solely on cloud storage for backups?

Relying solely on cloud storage for backups can be risky because cloud storage could be compromised by ransomware, and files may not be fully protected. It's important to also back up files on external drives or other methods.

What is a Virtual Private Network (VPN), and why is it recommended for public Wi-Fi use?

A VPN encrypts your internet connection, securing your data while you use public Wi-Fi. It prevents hackers from intercepting sensitive information such as passwords, credit card numbers, and personal details.
